BALING-PRESS.

SPECIFICATION forming part of Letters Patent No. 232,400, dated September 21, 1880.

Application filed August 3, 1880. (No model.)

To all whom it may concern:

Be it known that I, ALBERT A. GEERT, of Quincy, in the county of Adams and State of Illinois, have invented certain new and useful Improvements in Ealing-Presses; and I do hereby declare the following to be a full and exact description of the same, reference being had to the accompanying drawings, forming part of this specification, in Which- Io Figure l is a longitudinal section of a press embodying my invention, and Fig. 2 is a plan view of the bottom of the press-box.

Similar letters of reference in the several figures indicate the same parts.

This invention relates to improvements in that class ot' presses t'or which Letters Patent ot' the United States were granted me January 8, 1878, No. 199,052, and September 30, 1879, No. 220,019; and it consists, first, in forming 2o the bottom ot' the press-box of a series ot' rollers arranged with spaces between them, so as to form a screen through which to screen out all the dirt and trash from the material being s baled 5 and, secondly, in providing means for 2 5 resisting more or less the retraction or backward movement ofthe traverser to prevent shock.

In the drawings, A represents the press-box ot' the press, B the bale-chamber, C the feeding-hopper, into which the loose charges ofmaterial are pitched, and D the reciprocating traverser. The bottom of the press-box is composed of a series of rollers, a, arranged across the press parallel to each other, and with spaces between them, as shown. These rolle-rs may be journaled or supported in any suitable manner, but should in any case be capable ot revolving, in order that the dust, dirt, Sto., that falls upon them from the material may by their 4o revolution be carried out of the press-boX, and thus prevent the formation of a dirty side to the bale, as would be the case if no screening arrangement were employed.

In presses ot' this class the traverser is reversed by the reaction or back expansion of thepressed material, and ordinarily with such force as to cause a severe shock to the frame and power connections. To remedy this defeet I apply more or less friction to the trav- 5o erser during its backward movement, and thus stop its mot-ion gradually.

Various instrumentalities may be employed in carrying out this idea; but I prefer to adjust the lining orplanking E by means of an adjusting screw or screws, S, so as to cause it to bear upon the top ot the upper rear extension of the traverser, as shown in Fig. 1. By opera-ting the screw the lining or planking can be made to bear more or less tightly, as will be readily understood. The lining or plank- 6o ing may be made permanently contracted, if desired, and the same result be produced.

It has been customary to mount the power devices over the front axle ot the truck and connect saidtaxle to the frame of the press by means ot' a king-bolt or other equivalent arrangement, so as to permit the said axle to be turned. In consequence of this const-ruction there is always more or less swaying and rocking of the press while it is in operation, 7o To obviate this I now mount the power devices over the rear ixed axle, F, as shown, Fig. l, instead of over the movable front axle, as heretofore, and thus render the working of the press more even and uniform and prevent so much strain both on the frame and the power devices.

I claimas my invention- 1. Thepress-chamber of a baling-press having a screen-bottom, consisting ot' a series ot' 8o rollers, which revolve as the material is pushed along over them, and operate to keep the spaces between them clear and'unobstructed, substantially as described.

2. In a baling-press in which the traverser is reversed in Whole or in part by the reaction or back expansion ot' the pressed material, a friction-plate or pressure contrivance for applying friction to the traverser to retard its backward movement and prevent shock, sub- 9o sta-ntially as described.

3. The combination, with the traverser having the rearward extension, of the lining or planking and the set-screw for adjusting the same, substantially as described, tor the purpose specified. A
